Effective from 1st August 2019, we are pleased to announce that TRAILPARTS® has changed its legal status from a Partnership to a Private Limited Company, TRAILPARTS Ltd.
Adaptors & Leads
Having trouble connecting incompatible vehicle and trailer wiring plugs and sockets? TRAILPARTS® stocks a comprehensive range of products to enable you to overcome these challenges. Since European Whole Vehicle Type Approval legislation came into effect for small trailers in 2012, all new-build trailers must be fitted with a reverse lamp by law. This means that the old 7-pin wiring system is no longer suitable, and manufacturers must use a new 8-pin system.
As a consequence, it is very common to come up against incompatibility between trailer and vehicle wiring systems, and we have a number of products which provide a solution for this issue. Please browse our range and contact us if you have any queries.
TRAILPARTS® also stocks a large range of ready-made leads for a variety of applications ready to fit and use immediately, meaning there is no downtime while new leads are wired up. We have solutions for 7 pin and 8 pin applications, male-male, male-female, and an innovative solution for converting between 13 & 7 pin applications. Most leads are available in varying lengths and designs, and we can source other specs if required.
